Let me add the motto of William the Zwijger (the Taciturn), which was:
"Il n'est pas necessaire d'esperer pour entreprendre, ni de reussir pour
perseverer"
which can be freely translated as:
"It is not necessary to hope in order to try, nor is it necessary to succeed in
order to persevere",  which also seem to apply quite well to our LF work   :-)
